Illinois Capacitor''s PHC Series is a good example of an axial-lead film capacitor well suited for DC link applications (Figure 3.) In addition to low ESR (2.4 to 12.9 mW at 100 kHz and 25˚C) and high maximum ripple current (up to 14 A at 100 kHz), it''s axial-leaded design works well in circuits having point-to-point wiring.
